In what opera did Justice Ruth Bader Ginsberg make her debut?

When the curtain rose on Act 2 of a premiere of The Daughter of the Regiment by Donizetti in 2016, a tiny woman was barely visible in a large dome chair with her back to the audience. Suddenly, she swiveled around, and there was Justice Ruth Bader Ginsburg. When her character asked whether another woman could produce a birth certificate, she added the line: “We must take precautions against fraudulent pretenders.” (Barack Obama anyone?)
